After the success of the research on the process of breeding road-clawed crayfish in partly-running clear water, Ben Tre's Fishery Promotion Center is currently testing the new process to produce a new breed of allmale road-clawed crayfish. The process uses the hormone injection technique to stimulate the genetic process so that all the young crayfish will turn out to be male. This is said to be used in road clawed crayfish growing for export.

Some of the advantages of this method of breeding are that the crayfish can grow rapidly in weight and uniformly in size, and can produce higher profit.

Before, the Fishery Promotion Center has also successed in producing allmale tilapia, hence meeting the demand for high-quality products and diversification in the aquaculture industry.
